Researchers Discover New Ancestral Mechanism of Defense Against Nanoparticles

Posted by in categories: biological, nanotechnology

Scientists from the Finnish Hub for Development and Validation of Integrated Approaches (FHAIVE FHAIVE) and Tampere University have uncovered a novel response mechanism related to nanoparticle exposure that’s shared across various species.

A species is a group of living organisms that share a set of common characteristics and are able to breed and produce fertile offspring. The concept of a species is important in biology as it is used to classify and organize the diversity of life. There are different ways to define a species, but the most widely accepted one is the biological species concept, which defines a species as a group of organisms that can interbreed and produce viable offspring in nature. This definition is widely used in evolutionary biology and ecology to identify and classify living organisms.

Paralysed man walks again via thought-controlled implants

Posted by in categories: biotech/medical, neuroscience

A paralysed man has regained the ability to walk smoothly using only his thoughts for the first time, researchers said on Wednesday, thanks to two implants that restored communication between brain and spinal cord.

The patient Gert-Jan, who did not want to reveal his surname, said the breakthrough had given him “a freedom that I did not have” before.

The 40-year-old Dutchman has been paralysed in his legs for more than a decade after suffering a spinal cord injury during a bicycle accident.

A first step to designing better solid-state batteries

Posted by in categories: chemistry, climatology, sustainability

Electrifying transportation is an essential step towards mitigating climate change. To improve the power, efficiency and safety of electric vehicles, researchers must continue to develop better batteries.

All-solid-state lithium batteries (SSBs), which have a solid electrolyte instead of a liquid, are safer than traditional lithium-ion batteries because they are less flammable and more stable at higher temperatures. They could also have higher energy densities than lithium-ion batteries, allowing for longer lasting batteries in smaller sizes for portable electronics and other applications.

A research team led by Joshua Gallaway of Northeastern University in Boston and scientists at the Department of Energy’s (DOE) Argonne National Laboratory recently tested how the composition of thick cathodes affected electrochemical reactions in SSBs. The team used the resources of the Advanced Photon Source (APS), a DOE Office of Science user facility at Argonne. Their discoveries were published in the journal ACS Energy Letters.

OpenAI is exploring collective decisions on AI, like Wikipedia entries

Posted by in category: robotics/AI

May 22 (Reuters) — ChatGPT’s creator OpenAI is testing how to gather broad input on decisions impacting its artificial intelligence, its president Greg Brockman said on Monday.

At AI Forward, an event in San Francisco hosted by Goldman Sachs Group Inc (GS.N) and SV Angel, Brockman discussed the broad contours of how the maker of the wildly popular chatbot is seeking regulation of AI globally.

One announcement he previewed is akin to the model of Wikipedia, which he said requires people with diverse views to coalesce and agree on the encyclopedia’s entries.

Is this secretive device the “iPhone killer”?

Posted by in categories: computing, mobile phones

An ex-Apple exec who helped invent the iPhone is now trying to invent an “iPhone killer,” and thanks to a leaked video from a TED presentation, we now have our first glimpse at his secretive startup’s creation — but the available video only leads to more questions.

The startup: In 2016, Imran Chaudhri (then-director of design for Apple’s human interface team) and his wife Bethany Bongiorno (then-director for Apple’s operating systems team) quit the company to found their own startup: Humane.

Since then, the company has kept details of what it’s been working on close to its chest, but thanks to job openings posted on Humane’s website and some uncovered patent applications, by 2021, it seemed likely that the startup was developing some sort of personal tech device.

Telecom-wavelength quantum repeater node transmits quantum information over tens of kilometers

Posted by in categories: electronics, quantum physics

A quarter century ago, theoretical physicists at the University of Innsbruck made the first proposal on how to transmit quantum information via quantum repeaters over long distances, which would open the door to the construction of a worldwide quantum information network.

Now, a new generation of Innsbruck researchers has built a quantum repeater node for the standard wavelength of telecommunication networks and transmitted over tens of kilometers. The study is published in the journal Physical Review Letters.

Quantum networks connect quantum processors or quantum sensors with each other. This allows tap-proof communication and high-performance distributed sensor networks. Between network nodes, quantum information is exchanged by photons that travel through optical waveguides. Over long distances, however, the likelihood of photons being lost increases dramatically.
